It is found in the catchment’s grey box grassy woodlands, which are a focus of a Goulburn Broken CMA project that works with landowners, communities, and Traditional Owners to improve this critical habitat.
The plains brown tree frog was only “discovered” in 1971 by its call, which is slower than the call of its southern brown tree frog cousin.
Goulburn Broken CMA project officer Janice Mentiplay-Smith said the plains brown tree frog only occupied a small part of northern Victoria and across the border into NSW.
“As its range is so small, we are very lucky to have it call our grey box woodland environment home,” Ms Mentiplay-Smith said.
“This little frog breeds all-year-round if conditions are right.
“The female lays her eggs in small clusters, anchoring them to emerging water reeds and rushes, so healthy waterways, including dams or ponds, are important.
In a wetter year, such as the one we are experiencing, she may even lay her eggs in flooded ditches or in depressions in paddocks.
“As the plains brown tree frog occupies such a small part of our country, it is important we know its population status and extent, as there is no ‘back up’ population should disease or similar disaster cause their numbers to crash.”
Australia has more than 240 frog species, with 20 per cent classified as threatened, however it’s expected the true figure is higher, which is where the help of the public comes in.
“All of us have the capacity to be a citizen scientist and the Australian Museum FrogID app is a wonderful way to contribute to our country’s frog knowledge,” Ms Mentiplay-Smith said.
“The app is crucial to understanding the real story of the state of our frog populations and works by recording and submitting frog calls, which are then analysed by the Australian Museum FrogID validators.
“More than 380,000 frog records submitted by more than 22,800 citizen scientists have been verified since 2017. But there needs to be more, there can never be enough data.”
